About Linq

Send and manage iMessage, RCS, and SMS conversations, attachments, phone numbers, payments, and webhooks through the Linq Partner API.

What an agent can do in Linq

Every Linq action is classed by the platform as a read, a change or a send. Reads run at once. Changes and sends are held for a person by default.

Runs at once (reads)

Looks things up in Linq without asking first. 25 actions.

  • Check Messaging CapabilityCheck whether a recipient can receive iMessage or RCS without sending a message. Linq permits only one capability check per 10 seconds; cache successful answers briefly (minutes, not days) instead of
  • Get AttachmentReturn metadata and current status for a Linq attachment referenced by a message. This metadata-only action does not download the file.
  • Get Available NumberSelect an available Linq sending number, optionally for recipients or a line type. Treat the returned vCard URL as sensitive and ephemeral.
  • Get ChatReturn one chat by ID, including participants, service, state, and health information.
  • Get Chat LocationReturn precise locations currently shared by contacts in a chat. Treat coordinates and addresses as sensitive and minimize retention.
  • Get ExperienceReturn one Linq experience and preserve its dynamic action field definitions. Discovery does not prove that required provider setup is complete.
  • Get MessageReturn one Linq message by ID with its content parts, sender, actual and preferred transport, delivery state, reply target, and timestamps.
  • Get PaymentRead a payment's financial state, amount, customer handle, merchant details, and any customer-action URL. Treat returned identifiers and hosted URLs as sensitive financial metadata.
  • Get Payment CredentialsReturn the complete, highly sensitive short-lived handoff used to reveal a ready payment's virtual card directly from the provider. The response includes provider, user_token, card_ref, and fetch_url
  • Get Payment Handle ConnectionRead the financial-consent connection status for a customer phone number or email. Query only a customer handle whose owner consented to this lookup; the response may include a transient connect_id fo
  • Get Payment ProviderRead the organization's onboarding status for a payment provider. This is a read-only financial setup check; a 404 is an execution failure and must not be interpreted as a normal disabled status.
  • Get Payment RequestReturn one payment request's amount, lifecycle status, checkout details, and provider join keys. This is read-only financial metadata; treat checkout URLs and customer or provider IDs as sensitive.

  • Get PollReturn an iMessage poll's current options, voters, and distinct voter count.
  • Get Reputation AuditReturn a Linq line reputation audit created with explicit approval. Audits are retained for no more than 24 hours.
  • Get Webhook SubscriptionReturn one Linq webhook subscription by ID, including its callback URL, event and phone filters, active state, and configured routing-header names.
  • List Blocked HandlesReturn phone numbers, email addresses, short codes, and sender IDs currently blocked account-wide from inbound and direct outbound messaging.
  • List ChatsReturn one page of chats, optionally filtered by sending line or participant, with a cursor for the next page.
  • List Contact CardsReturn Linq account contact-card identity data, optionally for one E.164 sending line.
  • List ExperiencesDiscover Linq experiences and their dynamic action fields. Availability in this response does not prove payment-provider onboarding is complete.
  • List MessagesReturn one page of messages from a chat, including content, sender, transport, delivery state, direction, reply target, and timestamps, plus a cursor for older messages.
  • List Message ThreadReturn one page containing the origin message and threaded replies, starting from any message in the thread. A message with no thread returns by itself.
  • List Payment RequestsReturn one newest-first page of payment requests for reconciliation, optionally filtered by lifecycle status. This is read-only financial metadata; checkout URLs and customer or provider IDs in result
  • List Phone NumbersReturn the connected Linq account's sending lines with line type, forwarding configuration, and reputation status.
  • List Webhook EventsReturn the webhook event types currently available for subscription on the connected Linq account.
  • List Webhook SubscriptionsReturn the connected Linq account's webhook subscriptions, including event and phone-number filters, target URLs, active state, and routing-header names.

Held for approval by default (changes and sends)

Held for a person's approval by default. The approval is recorded and the action is sent once, never twice, with 10 seconds to undo. 43 actions.

  • Add Chat ParticipantAdd an external participant to an existing group chat. The participant-visible change is queued asynchronously.

  • Block HandleBlock a handle account-wide from inbound and direct outbound messaging. Pair controlled test blocks with UNBLOCK_HANDLE cleanup.
  • Cancel PaymentIrreversibly cancel a financial payment and close its virtual card. Confirm the payment identifier and authorization before calling because the canceled payment cannot be resumed.

  • Delete Webhook SubscriptionPermanently delete a Linq webhook subscription and stop its future event deliveries.
  • Edit MessageIrreversibly change recipient-visible text in one part of a message sent within the last 15 minutes. Linq permits at most five edits per message. A response with no message fields means Linq accepted

  • Revoke Payment Handle ConnectionIrreversibly revoke this partner's financial-consent grant for a customer phone number or email. This prevents future payments through the grant but does not delete the customer's provider wallet; rev
  • Send MessageSend one irreversible, externally visible message to phone numbers or emails. Linq reuses a matching chat or creates one and automatically selects the sending line.

  • Send Voice Memo to ChatIrreversibly send recipient-visible audio as a native iMessage voice memo bubble to every participant in an existing Linq chat.
  • Set Chat BackgroundSet a recipient-visible color, animated, or photo transcript background. Linq processes the change asynchronously.

  • Update Contact CardUpdate the public contact-card identity for one Linq sending line.
  • Update iMessage App CardIrreversibly send a recipient-visible in-place update to an iMessage app card. The update creates a new message version; use its returned message ID for the next serialized update.
  • Update Message ReactionIrreversibly mutate recipient-visible reaction state by adding or removing a tapback, or by adding an iMessage sticker. Stickers cannot be removed.
  • Update Phone NumberChange a Linq sending line's production forwarding configuration. Capture the current value before changing it when rollback is required.
