PortingExperimental

Abandon porting and keep the temporary number

Irreversibly gives up on porting for this eSIM: the temporary number becomes permanent and the eSIM activates asynchronously. Read the eSIM's lifecycleStatus to observe activation. Allowed only when the referenced request is the latest one and it is terminal (rejected, failed, or cancelled). After abandoning, further port-in requests for this eSIM are rejected.

Authorization

Authorization: Bearer {token} — an OAuth2 access token from the client-credentials flow. How authentication works

Path parameters

profileReferencestringrequired

The eSIM's profile reference (16-digit numeric string)

esimReferencestringrequired

eSIM reference identifier (18-digit opaque token)

portInRequestReferencestringrequired

Public port-in request reference (8-char uppercase base36)

Headers

X-Idempotency-Keystring

Optional idempotency key for mutating requests (POST, PATCH). If provided, duplicate requests with the same key within 48 hours will return the cached original response without duplicating side effects.

Behavior:

Same key + same request body → returns cached response (prevents duplicate operations)
Same key + different request body → returns 422 error
Same key + in-flight request → returns 409 error with Retry-After header
Keys expire after 48 hours

Request Body Matching: Request bodies are compared by their JSON content. Object key order, including in nested objects, and whitespace do not affect matching. This means:

{"a":1,"b":2} and {"b":2,"a":1} are treated as identical ✓
Whitespace differences are ignored ✓
URL parameters and headers are NOT included in request body matching

Best Practices:

Use UUIDs or client-generated unique strings
Store keys on your side to support retries
Don't reuse keys across different operations

Donor details of a Belgian number. A prepaid contract takes donorIccid and/or donorSimNumber; a postpaid contract any of donorIccid, donorSimNumber and donorAccountNumber; a business contract donorAccountNumber only.

ICCID of the donor SIM card, with a valid check digit. The preferred proof of a donor SIM: most donor operators accept it.

The number printed on the donor SIM card. Send it only when the donor SIM's ICCID is not available; donorIccid is accepted by more donor operators.

statusstring

Extensible enum.

requested: Accepted by Firsty; provider submission in progress
approved: The donor accepted the port; scheduledAt is when the number moves, once known, which can be days ahead. The port finishes at completed
cancelling: Cancellation requested, awaiting provider confirmation
completed: The donor released the number and it is assigned to this SIM
rejected: Donor rejected the request (see reason); submit a corrected request. A rejection the customer can still correct may keep the request requested until it is final
failed: Port failed (see reason); submit a corrected request
cancelled: Cancellation confirmed; the eSIM stays pre-active for a corrected request or abandon
