ITMS API — POST /api/v1/transactions/create-or-adjust

Create a committed invoice or atomically revision-adjust the active document behind the same logical code.

POST/api/v1/transactions/create-or-adjust

Create a committed invoice or atomically revision-adjust the active document behind the same logical code.

Persistence: Creates an immutable reversal and replacement when the business payload changes; identical retries replay the matching revision.
Auth: API key · scope transactions:write
Request: Committed transaction payload plus optional adjustmentReason. Send a stable Idempotency-Key on retries.
Response: The created or active replacement transaction, including revision lineage and idempotent_replay.

Request template for this operation

Set ITMS_API_KEY to a key with the scope shown above. Use a sandbox key while developing. Create request.json from this operation’s OpenAPI request schema for cURL, and set ITMS_REQUEST_BODY to that same JSON for JavaScript or Python. Do not copy production customer data into a sandbox request.

Request and response shape

Request: Committed transaction payload plus optional adjustmentReason. Send a stable Idempotency-Key on retries.
Response: The created or active replacement transaction, including revision lineage and idempotent_replay.

The versioned OpenAPI document is the machine-readable authority for required fields, types, enums, response schemas, and status codes. This page supplies the product and workflow context around that contract.

Integration contract

Use a key whose environment, organization, location, and scopes match the operation.
Validate the request against the customer OpenAPI document; never infer omitted required facts.
For create, apply, commit, refund, adjustment, or replay operations, follow the documented idempotency and duplicate semantics.
Persist the response request ID, result authority, warnings, and evidence references needed to reproduce the decision.
Handle the machine-readable error envelope and honor rate-limit retry headers.
