Add a caller rule

POST
/v1/caller_rules
curl --fail-with-body -X POST 'https://api.talki.it/v1/caller_rules' \
-H "Authorization: Bearer $TALKI_API_KEY" \
-H "Idempotency-Key: block-spam-1" \
-H "Content-Type: application/json" \
--data '{"phone_number":"+393401234567","kind":"blocked","label":"Telemarketing"}'

Add a number to the VIP or blocked list: 201 with the new rule. A number that already has a rule answers 200 with it, moved or relabelled as the request asks, or unchanged. Requires Idempotency-Key. Requires contacts:write. Limited to 120 requests per minute per account (API key) or per installation (OAuth), and to 20 creations per minute shared by the services, resources, tags and caller rules you create.

location_id
Any of:
string

The location to add the number at, an id from GET /v1/locations (inactive ones included). Omit it for the main location.

Talki-Version
string
Example
2026-10-01

Serve this one request at the given dated contract version instead of the credential’s pin. An unsupported value is refused with 400 unsupported_version, never downgraded.

Idempotency-Key
required
string
<= 255 characters

Unique key for this logical write. Reuse it only when retrying the same method, path, query and body. Required on appointment writes, on creating a service, a resource, a closure, a tag, a caller rule or a document, and on teaching the assistant; optional on every other write. Retained for 24 hours: a retry with the same key gets the first response again, marked Idempotency-Replayed: true, and a refusal that holds until the state changes (a time taken, a list full) is replayed too. A response a retry can change is not kept when the request saved nothing, and the retry runs the request again: a 400 asking for a different request (invalid_parameter, invalid_cursor, export_too_large, unknown_scenario, no_services_requested, stay_too_short, stay_too_long, stay_dates_invalid), a 415, a 409 request_conflict, document_not_ready or check_in_progress, a 412, a 429 and a 5xx.

Example
block-spam-1
Media typeapplication/json
CallerRuleCreate

A number to add. 201 creates a rule; 200 means the number already had one, which was moved or relabelled as the request asks, or returned unchanged.

Except idempotency_key_reuse, the other refusals are replayed for 24 hours to a request with the same idempotency key: once the cause is gone, retry with a new key. request_conflict clears by itself and is not kept: retry with the same key.
