Fast Tracks supports a variety of SMS providers, if your business need a provider which is not a part of the list of supported providers then you can build this API.

Fast Track SMS Service

The Fast Track SMS service can be configured to send SMS requests to the Operator API endpoints listed below, which allows the Operator to manage the SMS provider. It supports sending messages and to get fetch delivery status. Sending is available for both single or batched SMS requests.
The following endpoints can be built as a part for your Operator API:

⬆️ POST /channels/sms/single

⬆️ POST /channels/sms/batch

The Operator can then forward these requests to the SMS provider for processing and answer back with the respective responses.
API format and responses need to be formatted as outlined below
It is important that the "meta" data outlined below is sent back to Fast Track in either Webhook or Polling so that conversion data can be stored correctly. Please refer to the shown examples and the tables underneath for further clarification.

Pre-Requisites

  1. Advice Fast Track if any rate limiting should be taken into consideration. (If you plan to implement rate limiting please contact Fast Track before, so we can guide you on supported implementation)
  2. Advice Fast Track if any batch maximums should be taken into consideration.
  3. Provide Fast Track with any credentials specific for the integrated providers (if required)
  4. Supported SMS formats are GSM7 & USC2

Send SMS (Single)

A single SMS send request will contain the data of each individual SMS in separate requests to the API.

Endpoint Implementation

Implement the endpoint in the format below to support single-send SMS through API.
⬆️ POST <operator-api-endpoint-url>/channels/sms/single

Request Header

The header of the sent request contains an "X-Api-Key" which is a token required to authenticate the API calls at the endpoint. This token needs to be passed on to Fast Track in order to make these requests.

Request Body Schema

Refer to the following example of a single SMS request sent by Fast Track. The description of each field is listed in the table below it.
KeyTypeDesctiption
activity.id
integer
A unique identifier of the SMS
activity.brand_id
integer
The unique identifier of the brand on Fast Track
activity.user_id
string
The unique identifier of the player
activity.activity_id
integer
The unique identifier of the activity setup in Fast Track
activity.action_group_id
integer
The unique identifier of the action group which the SMS originates from Fast Track
activity.trigger_hash
string
Trigger hash
activity.action_id
integer
The unique identifier of the individual action from Fast Track
content
string
The content of the SMS
recipient
string
The recipient number
sender_name
string
The sender name of the SMS
provider_name
string
The name of the integrated provider
encoding
string
Type of encoding of SMS. Can be "auto", "gsm7" or "usc2"

Expected Responses

The Operator API should return the responses for each individual SMS message respectively to avoid unrelated storage of SMS data.

Successful HTTP 200-299 JSON Response

The "sms_id" will be a unique identifier generated by the Operator API which allows Fast Track to identify that particular SMS message in order to update its delivery status after it is sent.

ERROR Non-200 response JSON Response

Erroneous responses are typically associated with HTTP status codes 400s or 500s. The response should contain an "error" field with a description to show what went wrong and assist with troubleshooting.
The responses from the Operator API will be handled differently depending on the class of the HTTP status code. The table below gives a summary of how the HTTP status are handled separately.
HTTP Status CodesDescription
200-299
Successfully Delivered. Fast Track will acknowledge the message and start processing the next message in the queue.
400-499
Non Successful. When receiving this error, Fast Track will skip the SMS message. Additionally, it will send its data to Failed Actions, if the service is enabled.
500 or any other status code which is not listed above
Non Successful. The service fatals and Fast Track will keep retrying until a 200 response is received.

Batch SMS

Batch SMS helps to process a collection of SMS in one request to the API. The number of messages within the batch request is limited by a set integer amount in the configuration and sent within a configured time span, even when the batch is not yet full.

Endpoint Implementation

Implement the endpoint in the format below to support batch-send SMS through API.
⬆️ POST <operator-api-endpoint-url>/channels/sms/batch

Request Header

The header of the sent request contains an "X-Api-Key" which is a token required to authenticate the API calls at the endpoint. This token needs to be passed on to Fast Track in order to make these requests.

Request Body Schema

Here is an example of expected format when batching the requests. It is similar to the Single SMS request but the requests are stored in an array, one after the other.
KeyTypeDescription
activity.id
integer
A unique identifier of the SMS
activity.brand_id
integer
The unique identifier of the brand on Fast Track
activity.user_id
string
The unique identifier of the player
activity.activity_id
integer
The unique identifier of the activity setup in Fast Track
activity.action_group_id
integer
The unique identifier of the action group which the SMS originates from Fast Track
activity.trigger_hash
string
Trigger hash
activity.action_id
integer
The unique identifier of the individual action from Fast Track
content
string
The content of the SMS
recipient
string
The recipient number
sender_name
string
The sender name of the SMS
provider_name
string
The name of the integrated provider
encoding
string
Type of encoding of SMS. Can be "auto", "gsm7" or "usc2"

Expected Responses

The below responses should be returned by the Operator API.

Successful HTTP 200 JSON Response

The "activity.id" initially sent in the request will be returned back in the response as "id". This is required to help Fast Track identify the individual SMS message in the initial batch request. The "sms_id" will be a unique identifier generated by the Operator API, which Fast Track will use to identify the related SMS message when updating its status. If any of the listed categories ("successful", "failed" or "fatal") do not have an associated SMS, they should be returned as an empty array.
The request need to include one of the properties successful, failed or fatal
The logic flow on how the response will be handled is very similar to how the HTTP status codes are handled in the Single SMS. The sole difference is that the response with a status code 200 will be handled instead, according to the message's category in the response.
Response CategoryDescription
successful
Successfully Delivered. Fast Track will acknowledge the message and start processing the next batch in the queue.
failed
Non Successful. When receiving this error, Fast Track will skip the SMS message. Additionally, it will send its data to Failed Actions, if the service is enabled.
fatal
Messages will be retried
Any other messages that are not listed within the response will be retried.

ERROR (non 500 response) JSON Response

Fast Track will only support HTTP Status Code 200 in batching. The whole batch request will be retried if any other status code is received with the following response.

Conversion Data

We support retrieving conversion data through webhook.

Webhook

Fast Track will provide a Webhook URL & X-API-KEY that you can send the conversion data for each SMS.
The X-API-KEY supplied is expected as a header in the request.
It's important that the "activity" data which is provided from Fast Track in the Send SMS request is sent back
