Remove iMessage contact profile picture
Removes the custom profile picture and keeps the names when expectedVersion matches. An identical configuration keeps its version after verification. Returns 200 after confirmation and commit, 202 while pending, or a problem on failure. Repeat the same request with the same Idempotency-Key after Retry-After to await the result. Results are retained for 24 hours; key replay precedes version validation. A different change while one is pending returns 409. Requires platforms:write bound to the path project.
Authorizations
Account Service Key, prefixed with pho_ask_, sent as Authorization: Bearer <key>. Acts on behalf of its owning account, subject to the permissions and credential restrictions of each operation. Account access tokens and OAuth grants also use the Bearer header. In organizations that require SSO, Account Service Keys are not accepted for managing the organization's SSO settings, deleting the organization, or checking whether it can be deleted.
