}- Credential: an API key. See Activation.
- Account: wholesale partners only: any other account receives
402 checkout_required. A direct account buys a line in the iSnap dashboard: see Accounts. - Line-scoped keys: a line-scoped key gets
403 forbiddenunless the line is in its list. - Test keys: an activation sent with an
isnap_test_account key activates a real line, billed like any other: see Test keys. Idempotency-Key: not honored. After a lost response, readGET /v1/lines/mybefore you call again: see Retries.- Events: none. See Events.
Errors
| Status | error.code | When |
|---|---|---|
| 400 | validation_failed | The body is invalid: for example, billing_anchor_at is not an ISO 8601 timestamp with a Z suffix. |
| 400 | billing_anchor_too_far | billing_anchor_at is more than 31 days after the activation. |
| 400 | inbound_only_not_rental | inbound_only is true and the line is not a rented line. |
| 400 | A code that starts with line_ | The reserved line can no longer be acquired. The codes are those of reserve, with status 400 here. Release the line and choose another one. |
| 402 | checkout_required | Your account is not a wholesale partner. |
| 403 | forbidden | The request uses a line-scoped key, and the line is not in its list. |
| 409 | line_not_reserved | The line is not reserved by your account within the 15 minutes: the reservation expired or was released, the line was never reserved, or no line has this id. |
| 409 | line_already_subscribed, subscription_cancel_failed | The line carries a per-line subscription that could not be closed. |
Authorizations
An API key created in the iSnap dashboard, or a trial key, sent as Authorization: Bearer <key>. An API key starts with isnap_live_ or isnap_test_; both act on the same account, lines and billing. A trial key acts on its trial only.
Path Parameters
Id of a line: line_ followed by 25 letters or digits.
^line_[0-9A-Za-z]{25}$Body
Optional settings of the activated line: its variant and its billing anchor.
true to activate the line as an inbound-only line. Rented lines only (400 inbound_only_not_rental otherwise). Defaults to false: a two-way line.
The billing anchor of the line: an ISO 8601 timestamp in UTC, with a Z suffix. A line billed on the monthly wholesale invoice is charged one full month at each monthly occurrence of this timestamp: the same day of the month, moved to the last day of a shorter month, at the same time of day. At the first occurrence after its activation, the line is also credited for the days that the month charged at activation had already paid for past that occurrence. Omit it to bill the line at each monthly occurrence of its activation. A past timestamp is accepted. A timestamp more than 31 days after the request returns 400 billing_anchor_too_far.
"2026-09-11T09:15:00Z"
Response
The activated line.
Always true on a success response.
true A line. billing_tier, byod, shared, test_line and inbound_only tell the kinds of line apart: a rented line (two-way or inbound-only), a BYOD line, a shared line, a test line.
