The adjuster can no longer accept it, and its status becomes `withdrawn`. You can invite the same adjuster again later. If the adjuster has already accepted, the request fails with `409 already_member`. If there is no pending invitation for that OSAID in your firm, it fails with `404 not_found`. ## OpenAPI ````yaml /openapi.yaml delete /v1/adjusters/invitations/{osa_id} openapi: 3.1.0 info: title: OSA Partner API version: 1.0.0 summary: Send claims to adjusters in the OSA app and follow their acceptance. description: > The OSA Partner API lets an adjusting firm's claims system invite adjusters to the firm, send them claims, and see whether each claim was accepted or rejected in the OSA app. **Conventions** - All requests and responses are JSON (`application/json`); errors use RFC 9457 problem details (`application/problem+json`). - Field names are `snake_case`. Enum values are lowercase (for example `flood`, `pending_acceptance`), except US state and territory codes, which are the standard two-letter USPS codes, and flood zones, which are written as FEMA writes them (for example `AE`). - Enums are **open**: new values may be added to responses at any time, so your code must tolerate values it doesn't recognise. - Additive changes (new endpoints, new optional request fields, new response fields, new enum values) are made within `/v1`. Breaking changes go to a new version. - Requests are strict: an unknown or misspelled body field or query parameter is rejected with `422 validation_failed`, so typos can't be silently ignored. - Your own claim id (`external_id`) is stored on every claim and returned on every claim response, so you can match claims without keeping OSA's id. - Timestamps are RFC 3339 date-times in UTC. Dates that are calendar dates (such as the date of loss) are `YYYY-MM-DD` and are never converted between time zones. **Keys.** Every request except `GET /v1/health` needs an API key sent as `Authorization: Bearer `. Live keys start with `osa_live_`; test keys start with `osa_test_` and only reach test claims and test accounts. contact: name: OSA API support email: info@osaconnection.com url: https://docs.osaconnection.com servers: - url: https://api.osaconnection.com description: >- Production.
