La référence ci-dessous est en anglais.

Authentication

All API requests require authentication using an API key passed in the X-API-Key header.

Example Request

curl -H "X-API-Key: tg_live_your_api_key" \
  https://api.tellandgo.com/api/v1/agent/search

tg_live_*

Production keys

Use for live production applications. Real data and billing.

tg_test_*

Test/sandbox keys

Use for development and testing. No real bookings created.

Rate Limits

API requests are rate limited based on your subscription tier.

Tier	Rate Limit	Commission
Free	100/hour	Up to 2% (margin-capped)
Enterprise	By arrangement	Custom (margin-capped)

Commission: up to 2% of the booking value on completed bookings, capped per booking so Tell & Go keeps its minimum margin after card fees; bookings with thin margins may earn a lower rate or none.

Body Parameters

success_url	string	Optional	Optional HTTPS URL to return the payer to after Stripe-hosted checkout succeeds. booking_id and session_id are appended when missing.
cancel_url	string	Optional	Optional HTTPS URL to return the payer to if Stripe-hosted checkout is cancelled. booking_id and payment=cancelled are appended when missing.

Request Body

{
 "quote_id": "quote_xxx",
 "guests": [
   {
     "first_name": "John",
     "last_name": "Doe",
     "email": "john@example.com",
     "is_primary": true
    }
  ],
 "special_requests": "Honeymoon celebration",
 "payment_method": "stripe_checkout",
 "success_url": "https://partner.example/bookings/complete",
 "cancel_url": "https://partner.example/bookings/cancelled"
}

Final Booking Status

Payment success does not by itself mean the hotel booking is confirmed. Stripe returns the customer after payment, while Tell&Go finalizes the booking server-to-server and updates the stored booking status.

Call /book with payment_method=stripe_checkout.
Redirect the customer to booking.payment.url.
If you provide success_url and cancel_url, Stripe returns the customer to your URLs. Tell&Go appends booking_id and session_id when they are missing.
If you do not provide return URLs, Stripe returns the customer to Tell&Go’s default booking status page. That page may initially show “Payment received, confirming your booking” while backend confirmation is still running.
Treat GET /bookings/:id and partner webhooks as the canonical final-status mechanisms.

Partners do not call Tell&Go’s inbound /webhook endpoints; those are reserved for payment and supplier callbacks into Tell&Go.

Manage Bookings

List, retrieve, and cancel bookings.

GET/bookingsList all bookings

GET/bookings/:idGet booking details

DELETE/bookings/:idCancel booking

Partner Webhooks

Register a partner-owned HTTPS callback URL to receive async booking status events. Webhook management requires an authenticated partner API key with the webhooks:write scope. Endpoint records are scoped to the authenticated partner.

Final Status Events

For hotel checkout final status, subscribe to payment.failed, booking.confirmed, and booking.failed.

Endpoints

POST/webhooks/endpointsCreate a webhook endpoint

GET/webhooks/endpointsList your webhook endpoints

PATCH/webhooks/endpoints/:idUpdate your endpoint URL, events, description, or active state

POST/webhooks/endpoints/:id/testSend a signed test event

DELETE/webhooks/endpoints/:idDisable an endpoint

GET/webhook-deliveriesList recent delivery attempts

Create Example

curl -X POST https://api.tellandgo.com/api/v1/agent/webhooks/endpoints \
  -H "X-API-Key: tg_live_your_api_key" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://partner.example/webhooks/tellandgo",
    "events": ["booking.confirmed", "booking.failed", "payment.failed"],
    "description": "Production booking status webhook"
  }'

The create response returns a secret once. Store it securely; list and update responses do not return it.

Signature Verification

Tell&Go sends Tellandgo-Event, Tellandgo-Timestamp, and Tellandgo-Signature. Verify HMAC-SHA256 over ${timestamp}.${rawBody} with the endpoint secret and compare it with the v1 value from the signature header. Reject stale timestamps and always verify against the raw request body.

Tell&Go retries transient failures, including network errors, HTTP 429, and HTTP 5xx responses, up to three total attempts. Other HTTP 4xx responses are treated as non-retryable configuration errors.

Error Handling

All errors follow a consistent format.

Status	Code	Description
400	bad_request	Invalid request parameters
401	unauthorized	Invalid or missing API key
404	not_found	Resource not found
429	rate_limited	Rate limit exceeded

Error Response Format

{
  "error": "bad_request",
  "message": "Missing required field: property_id"
}
