Linq

Tools

• Add Chat Participant

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

• Add Poll Options

  Irreversibly add recipient-visible options to an existing iMessage poll. Poll options cannot be edited or removed after they are added.

• Block Handle

  Block a handle account-wide from inbound and direct outbound messaging. Pair controlled test blocks with UNBLOCK_HANDLE cleanup.

• Cancel Payment

  Irreversibly cancel a financial payment and close its virtual card. Confirm the payment identifier and authorization before calling because the canceled payment cannot be resumed.

• Cancel Payment Request

  Irreversibly cancel an unpaid payment request and its underlying payment intent. The checkout can no longer be completed after cancellation; paid, canceled, or expired requests cannot be canceled. Confirm the request ID and intent first.

• Check Messaging Capability

  Check 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 checking before every send.

• Connect Payment Handle

  Start the financial-consent ceremony for a customer phone number or email so an agent can later pay on that customer's behalf. This consent-sensitive, irreversible action may contact the customer and send an OTP; call it only with the custo

• Create Chat

  Create or reuse a chat on an explicit sending line and send an irreversible recipient-visible initial message. First-message text and parts cannot contain links.

• Create Payment

  Create or advance a real financial payment on a connected customer's behalf, potentially minting a single-use virtual card. This is consent-sensitive and financially consequential; obtain explicit customer authorization, verify the amount a

• Create Payment Request

  Create a customer-facing checkout that can collect a one-time charge or start an auto-renewing subscription. This creates financial state but does not itself send the checkout URL to a recipient. Confirm the amount, currency, mode, rail, an

• Create Poll

  Irreversibly send a recipient-visible iMessage poll to an existing chat. A poll cannot be the chat's first message, and its options are add-only and immutable.

• Create Webhook Subscription

  Create a webhook subscription for selected Linq events at a controlled HTTPS callback. The response includes a one-time signing secret that must be stored securely.

• Delete Attachment

  destructive

  Permanently delete a Linq attachment and its stored bytes.

• Delete Message

  destructive

  Irreversibly delete a message record from Linq. This does not unsend the message or remove it from recipients' devices, and its idempotency key cannot be reused to resend it.

• Delete Webhook Subscription

  destructive

  Permanently delete a Linq webhook subscription and stop its future event deliveries.

• Edit Message

  Irreversibly 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 an edit for a deleted message.

• Get Attachment

  Return metadata and current status for a Linq attachment referenced by a message. This metadata-only action does not download the file.

• Get Available Number

  Select an available Linq sending number, optionally for recipients or a line type. Treat the returned vCard URL as sensitive and ephemeral.

• Get Chat

  Return one chat by ID, including participants, service, state, and health information.

• Get Chat Location

  Return precise locations currently shared by contacts in a chat. Treat coordinates and addresses as sensitive and minimize retention.

• Get Experience

  Return one Linq experience and preserve its dynamic action field definitions. Discovery does not prove that required provider setup is complete.

• Get Message

  Return one Linq message by ID with its content parts, sender, actual and preferred transport, delivery state, reply target, and timestamps.

• Get Payment

  Read 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 Credentials

  Return 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 when supplied. Use it only for the immed

• Get Payment Handle Connection

  Read 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 for a pending ceremony.

• Get Payment Provider

  Read 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 Request

  Return 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 Poll

  Return an iMessage poll's current options, voters, and distinct voter count.

• Get Reputation Audit

  Return a Linq line reputation audit created with explicit approval. Audits are retained for no more than 24 hours.

• Get Webhook Subscription

  Return one Linq webhook subscription by ID, including its callback URL, event and phone filters, active state, and configured routing-header names.

• Leave Chat

  Leave an iMessage group chat. This is irreversible and prevents further interaction through the sending line.

• List Blocked Handles

  Return phone numbers, email addresses, short codes, and sender IDs currently blocked account-wide from inbound and direct outbound messaging.

• List Chats

  Return one page of chats, optionally filtered by sending line or participant, with a cursor for the next page.

• List Contact Cards

  Return Linq account contact-card identity data, optionally for one E.164 sending line.

• List Experiences

  Discover Linq experiences and their dynamic action fields. Availability in this response does not prove payment-provider onboarding is complete.

• List Messages

  Return 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 Thread

  Return 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 Requests

  Return 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 results are sensitive.

• List Phone Numbers

  Return the connected Linq account's sending lines with line type, forwarding configuration, and reputation status.

• List Webhook Events

  Return the webhook event types currently available for subscription on the connected Linq account.

• List Webhook Subscriptions

  Return the connected Linq account's webhook subscriptions, including event and phone-number filters, target URLs, active state, and routing-header names.

• Mark Chat As Read

  Mark every message in a chat as read and send an irreversible read receipt.

• Remove Chat Background

  destructive

  Reset a chat's recipient-visible transcript background to the default.

• Remove Chat Participant

  destructive

  Remove an external participant from a group chat. This irreversibly changes recipient-visible conversation membership.

• Request Attachment Upload

  Reserve persistent attachment storage and return a 15-minute presigned upload URL. This action does not upload file bytes; PUT the raw bytes separately to the returned opaque URL using the exact required_headers.

• Request Chat Location

  Prompt a contact in a one-to-one iMessage chat to consent to sharing their precise location. This is recipient-visible and rate-limited per chat.

• Revoke Payment Handle Connection

  destructive

  Irreversibly 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; revoke only with explicit authorization.

• Send Message

  Send 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 Message to Chat

  Send one follow-up or threaded reply to an existing Linq chat using its established sending line. This creates an irreversible recipient-visible message.

• Send Voice Memo to Chat

  Irreversibly send recipient-visible audio as a native iMessage voice memo bubble to every participant in an existing Linq chat.
