A second live policy for the asset refuses 409 `DUPLICATE_POLICY`. Reference: https://docs.immix.xyz/api-reference/rest-api/asset-policies/create ## Authentication - `Authorization` header (bearer token, required) — Bearer authentication of the form `Bearer `, where token is your auth token. ## Request ### Headers - `Idempotency-Key` (string, required) — Required on every write: a URL-safe string of 1 to 64 characters from `[A-Za-z0-9._~-]` (a UUID fits), scoped to you. It names one operation on one record, ever: a retry replays the stored outcome (`Idempotent-Replay: true`) or attaches to the live one, and reuse on another record refuses 409 `IDEMPOTENCY_KEY_REUSED`. Missing or malformed, 400. ### Body (application/json) This endpoint expects a SubmitAssetPolicyBody. - `assetId` (integer, required) - `assetPolicyId` (integer, optional) — 0 = create. - `expectedVersion` (string, optional, nullable) — int64 as a decimal JSON string - `maxTicketAmount` (string, optional, nullable) — money (a Decimal on the wire): a decimal string on input, encoded at its own scale — the fractional digits sent, trailing zeros dropped, at most 18. The edge consults no reference data: a value finer than its record is the platform's to judge, not the edge's to refuse; absent, null or "0" = unset (the 0 sentinel) - `approvalThresholdAmount` (string, optional, nullable) — money (a Decimal on the wire): a decimal string on input, encoded at its own scale — the fractional digits sent, trailing zeros dropped, at most 18. The edge consults no reference data: a value finer than its record is the platform's to judge, not the edge's to refuse; absent, null or "0" = unset (the 0 sentinel) - `reconciliationToleranceAmount` (string, optional, nullable) — money (a Decimal on the wire): a decimal string on input, encoded at its own scale — the fractional digits sent, trailing zeros dropped, at most 18. The edge consults no reference data: a value finer than its record is the platform's to judge, not the edge's to refuse; absent, null or "0" = unset (the 0 sentinel) - `openingGraceNs` (string, optional, nullable) — int64 as a decimal JSON string ## Response ### 200 The asset policy as the platform now holds it after the write — the same row the read serves, with the answering change's position, the row's `ETag` and, on a replayed key, `Idempotent-Replay`. - `assetId` (integer, required) — Refdata reference — carried, not resolved here. - `assetPolicyId` (integer, required) — Sticky entity key. - `globalSequence` (string, required) — The position as a decimal string — the last change this member had applied, orders and balance readings included. - `orgId` (integer, required) — Owner-stamped. - `pendingTransition` (enum, required) — ACTIVATE, AMEND or RETIRE; NONE otherwise. NONE is the unset sentinel: outputs only — as input, omit the field instead; explicit NONE refuses 400. The value set is append-only: a consumer READING this field treats an unknown name as NONE, never as an error; as input an unknown name refuses 400 — the parse is strict - Allowed values: `NONE`, `ACTIVATE`, `AMEND`, `REACTIVATE`, `UNFREEZE`, `RETIRE`, `REVOKE`, `ROTATE`, `RESUME_TRADING` - `status` (enum, required) — UNKNOWN is the unset sentinel: outputs only — as input, omit the field instead; explicit UNKNOWN refuses 400. The value set is append-only: a consumer READING this field treats an unknown name as UNKNOWN, never as an error; as input an unknown name refuses 400 — the parse is strict - Allowed values: `UNKNOWN`, `DRAFT`, `PENDING_APPROVAL`, `ACTIVE`, `RETIRED` - `version` (string, required) — The row's version — monotonic per record, bumped on every change; served as the ETag and taken by If-Match. int64 as a decimal JSON string - `approvalThresholdAmount` (string, optional, nullable) — Transfers at or above this amount require an approval; 0 = every transfer requires approval (the fail-safe reading). money (a Decimal on the wire: a scaled integer with its own scale), served as an exact decimal string at the value's own scale — every fractional digit that scale states, trailing zeros included; never raw; null when the 0 sentinel means unset - `maxTicketAmount` (string, optional, nullable) — Per-transfer ticket cap; 0 = no cap. money (a Decimal on the wire: a scaled integer with its own scale), served as an exact decimal string at the value's own scale — every fractional digit that scale states, trailing zeros included; never raw; null when the 0 sentinel means unset - `openingGraceNs` (string, optional, nullable) — The activation grace window, held as sequenced state so every member derives the same ledger from it; 0 = no window — no observation auto-posts opening equity (the strict reading). int64 as a decimal JSON string - `pendingByUserId` (integer, optional, nullable) — The user whose proposal is pending, so an approver is checked to be someone else; 0 when nothing is pending. - `reconciliationToleranceAmount` (string, optional, nullable) — The tolerance a reconciliation comparison allows; 0 = an exact match is required (fail-safe: tighter and noisier, never looser). money (a Decimal on the wire: a scaled integer with its own scale), served as an exact decimal string at the value's own scale — every fractional digit that scale states, trailing zeros included; never raw; null when the 0 sentinel means unset - `unscaled` (boolean, optional, deprecated) — Never present since 0.3.3: every money value on this API states its own scale on the wire — a policy amount or cap since 0.3.3, an order's and an execution's since 0.3.2, a balance's since 0.3.1 — so a row is never served raw, whether or not this member holds the asset or instrument it references. Kept, deprecated, so a client generated from 0.3.2 still compiles; it goes at the next major. ## Errors ### 400 Create Asset Policies Request Bad Request Error Refused at the door — nothing reached the platform and the key was not journaled: a missing or malformed `Idempotency-Key` or `If-Match`, malformed JSON, a body `userId`, a body restating the path or `If-Match` differently, a money string off its `pattern` (an exponent, a plus sign, a bare point, surrounding whitespace) or past its `maxLength`, or one no value here can state (over 18 fractional digits, or past a 64-bit integer at its own scale), or any other value outside the schema. - `error` (ErrorError, required) - `currentVersion` (string, optional) — On 412 `VERSION_CONFLICT`: the row's current version (the `ETag` carries the same token) — re-read, reapply, retry. ### 401 Create Asset Policies Request Unauthorized Error No bearer token, or one that does not verify. - `error` (ErrorError, required) - `currentVersion` (string, optional) — On 412 `VERSION_CONFLICT`: the row's current version (the `ETag` carries the same token) — re-read, reapply, retry. ### 403 Create Asset Policies Request Forbidden Error Authenticated, but not admitted. `FORBIDDEN_PRINCIPAL`: a token with no `org_id`, a non-ASCII `org_id` or `sub`, a disabled user, or a local binding with no user. `AWAITING_ADMISSION`: your user is not yet admitted — every route but `GET /me` answers this until an administrator admits you. `ORG_NOT_ACTIVE`: your organisation is suspended, pending activation, retired or unregistered. The record owners' 403s (`CAPABILITY_DENIED`, `SELF_APPROVAL`, `NOT_PROPOSER`, …) are refusals on the platform's stream: they carry the position header, and a retried key replays them with `Idempotent-Replay`. - `error` (ErrorError, required) - `currentVersion` (string, optional) — On 412 `VERSION_CONFLICT`: the row's current version (the `ETag` carries the same token) — re-read, reapply, retry. ### 409 Create Asset Policies Request Conflict Error The record owner's refusal, by class: 409 for a state or uniqueness refusal, 422 for a field or reference refusal — a fact on the platform's stream, so it carries the position header and a retried key replays it. The same statuses also carry two door refusals that are never journaled: 409 `IDEMPOTENCY_KEY_REUSED` and, on `POST /orders`, 422 `INSTRUMENT_NOT_LIVE` for a symbol this member holds no instrument under and 422 `ACCOUNT_NOT_ACTIVE` for a display name no live account of your org holds (the owner answers both codes, as facts, to an id it will not trade) — a retry takes fresh. - `error` (ErrorError, required) - `currentVersion` (string, optional) — On 412 `VERSION_CONFLICT`: the row's current version (the `ETag` carries the same token) — re-read, reapply, retry. ### 413 Create Asset Policies Request Content Too Large Error The platform refused the command's size (`TOO_LARGE`); nothing was submitted, a retry takes fresh. Not expected for any route here. - `error` (ErrorError, required) - `currentVersion` (string, optional) — On 412 `VERSION_CONFLICT`: the row's current version (the `ETag` carries the same token) — re-read, reapply, retry. ### 422 Create Asset Policies Request Unprocessable Entity Error The record owner's refusal, by class: 409 for a state or uniqueness refusal, 422 for a field or reference refusal — a fact on the platform's stream, so it carries the position header and a retried key replays it. The same statuses also carry two door refusals that are never journaled: 409 `IDEMPOTENCY_KEY_REUSED` and, on `POST /orders`, 422 `INSTRUMENT_NOT_LIVE` for a symbol this member holds no instrument under and 422 `ACCOUNT_NOT_ACTIVE` for a display name no live account of your org holds (the owner answers both codes, as facts, to an id it will not trade) — a retry takes fresh. - `error` (ErrorError, required) - `currentVersion` (string, optional) — On 412 `VERSION_CONFLICT`: the row's current version (the `ETag` carries the same token) — re-read, reapply, retry. ### 429 Create Asset Policies Request Too Many Requests Error Shed at once: `INBOX_FULL` or `IN_FLIGHT_FULL` (this member's bounds; nothing queued, the key not journaled), the intake's `RATE_LIMITED`, or the orders owner's `RATE_CEILING` (the organisation's per-minute ceiling — a refusal on the stream, replayed like any). `Retry-After` says when. - `error` (ErrorError, required) - `currentVersion` (string, optional) — On 412 `VERSION_CONFLICT`: the row's current version (the `ETag` carries the same token) — re-read, reapply, retry. ### 500 Create Asset Policies Request Internal Server Error The gateway failed to serve (`INTERRUPTED`, `INTERNAL_ERROR`, `PROJECTION_MISS`); the operation record, if one exists, is still readable. - `error` (ErrorError, required) - `currentVersion` (string, optional) — On 412 `VERSION_CONFLICT`: the row's current version (the `ETag` carries the same token) — re-read, reapply, retry. ### 503 Create Asset Policies Request Service Unavailable Error This member cannot carry the write now: `NOT_PRIMED` (still catching up), `NOT_SERVING` (a read-only or not-ready member), `OWNER_ABSENT` (the record owner has no active member), `INTAKE_UNAVAILABLE` (no credential store here), or the platform's own outcome for a command lost in transit. Nothing was journaled; retry against a serving member. - `error` (ErrorError, required) - `currentVersion` (string, optional) — On 412 `VERSION_CONFLICT`: the row's current version (the `ETag` carries the same token) — re-read, reapply, retry. ## Types ### ErrorError - `code` (string, required) — The code to branch on — stable and append-only: treat one you do not know by its HTTP status. The gateway's own: - 400: `MALFORMED_REQUEST`, `MISSING_IDEMPOTENCY_KEY`, `INVALID_IDEMPOTENCY_KEY`, `INVALID_IF_MATCH` - 401: `UNAUTHENTICATED` - 403: `FORBIDDEN_PRINCIPAL`, `AWAITING_ADMISSION`, `ORG_NOT_ACTIVE`, `CAPABILITY_DENIED` (the credential intake) - 404: `NOT_FOUND`, `UNKNOWN_OPERATION` - 409: `IDEMPOTENCY_KEY_REUSED`, `INTAKE_KEY_REUSED` - 413: `TOO_LARGE`, `PAYLOAD_TOO_LARGE` - 422: `INSTRUMENT_NOT_LIVE` and `ACCOUNT_NOT_ACTIVE` (`POST /orders`: a symbol or an account name nothing here holds — the orders owner answers the same codes to an unheld id), `VENUE_UNSUPPORTED`; `SCALE_UNKNOWN` (retired: only a member below `0.3.4` answers it) - 429: `INBOX_FULL`, `IN_FLIGHT_FULL`, `RATE_LIMITED` - 500: `INTERRUPTED`, `INTERNAL_ERROR`, `PROJECTION_MISS` - 503: `NOT_PRIMED`, `NOT_SERVING`, `OWNER_ABSENT`, `INTAKE_UNAVAILABLE`, `BALANCES_UNAVAILABLE`, `LOST`, `REJECTED_NOT_REGISTERED`, `REJECTED_NOT_ACTIVE` The record owners' refusals ride verbatim — `OrgRegisterRejected.reason` and `OrderRejected.reason` list them, and the guide's Errors section maps each to its status. - `message` (string, optional) — Free text for humans; may change without notice — never parse it. ## Examples **Request** ```json { "assetId": 1 } ``` **Response** ```json { "assetId": 1, "assetPolicyId": 1, "globalSequence": "globalSequence", "orgId": 1, "pendingTransition": "NONE", "status": "UNKNOWN", "version": "version", "approvalThresholdAmount": "approvalThresholdAmount", "maxTicketAmount": "maxTicketAmount", "openingGraceNs": "openingGraceNs", "pendingByUserId": 1, "reconciliationToleranceAmount": "reconciliationToleranceAmount" } ``` **SDK Code** ```python import requests url = "https://api.example.com/asset-policies" payload = { "assetId": 1 } headers = { "Idempotency-Key": "Idempotency-Key", "Authorization": "Bearer ", "Content-Type": "application/json" } response = requests.post(url, json=payload, headers=headers) print(response.json()) ``` ```javascript const url = 'https://api.example.com/asset-policies'; const options = { method: 'POST', headers: { 'Idempotency-Key': 'Idempotency-Key', Authorization: 'Bearer ', 'Content-Type': 'application/json' }, body: '{"assetId":1}' }; try { const response = await fetch(url, options); const data = await response.json(); console.log(data); } catch (error) { console.error(error); } ``` ```go package main import ( "fmt" "strings" "net/http" "io" ) func main() { url := "https://api.example.com/asset-policies" payload := strings.NewReader("{\n \"assetId\": 1\n}") req, _ := http.NewRequest("POST", url, payload) req.Header.Add("Idempotency-Key", "Idempotency-Key") req.Header.Add("Authorization", "Bearer ") req.Header.Add("Content-Type", "application/json") res, _ := http.DefaultClient.Do(req) defer res.Body.Close() body, _ := io.ReadAll(res.Body) fmt.Println(res) fmt.Println(string(body)) } ``` ```ruby require 'uri' require 'net/http' url = URI("https://api.example.com/asset-policies") http = Net::HTTP.new(url.host, url.port) http.use_ssl = true request = Net::HTTP::Post.new(url) request["Idempotency-Key"] = 'Idempotency-Key' request["Authorization"] = 'Bearer ' request["Content-Type"] = 'application/json' request.body = "{\n \"assetId\": 1\n}" response = http.request(request) puts response.read_body ``` ```java import com.mashape.unirest.http.HttpResponse; import com.mashape.unirest.http.Unirest; HttpResponse response = Unirest.post("https://api.example.com/asset-policies") .header("Idempotency-Key", "Idempotency-Key") .header("Authorization", "Bearer ") .header("Content-Type", "application/json") .body("{\n \"assetId\": 1\n}") .asString(); ``` ```php request('POST', 'https://api.example.com/asset-policies', [ 'body' => '{ "assetId": 1 }', 'headers' => [ 'Authorization' => 'Bearer ', 'Content-Type' => 'application/json', 'Idempotency-Key' => 'Idempotency-Key', ], ]); echo $response->getBody(); ``` ```csharp using RestSharp; var client = new RestClient("https://api.example.com/asset-policies"); var request = new RestRequest(Method.POST); request.AddHeader("Idempotency-Key", "Idempotency-Key"); request.AddHeader("Authorization", "Bearer "); request.AddHeader("Content-Type", "application/json"); request.AddParameter("application/json", "{\n \"assetId\": 1\n}", ParameterType.RequestBody); IRestResponse response = client.Execute(request); ``` ```swift import Foundation let headers = [ "Idempotency-Key": "Idempotency-Key", "Authorization": "Bearer ", "Content-Type": "application/json" ] let parameters = ["assetId": 1] as [String : Any] let postData = JSONSerialization.data(withJSONObject: parameters, options: []) let request = NSMutableURLRequest(url: NSURL(string: "https://api.example.com/asset-policies")!
