What you need to know about requests
All requests must be made using the HTTPS protocol. The request body must be sent in JSON format, or multipar/form-data for file upload.
Example:
http
POST /api/v1/shipments HTTP/1.1
Host: sandbox.tristarexpress.com
Content-Type: application/json
Accept: application/json
# Other headers
# Accept-Encoding: gzip, deflate
# User-Agent: ...
# Content-Length: ...
Responses in the desired format
To receive the responses in JSON, you must send the header Accept: application/xml in the request.
http
POST /api/v1/shipments HTTP/1.1
Host: sandbox.tristarexpress.com
Content-Type: application/json
Accept: application/json
Responses in other languages
For default responses will be in English, but you can change the response language by sending the Accept-Language header in the request. So error messages and other texts will be returned in the desired language.
http
POST /v1/shipments HTTP/1.1
Host: sandbox.tristarexpress.com
Content-Type: application/json
Accept: application/json
Accept-Language: pt-BR
Some times the desired language may not be available at the moment, in this case the response will be returned in the default language (en-US).
Date and time format
Our API uses the ISO 8601 format for dates and times. Example: 2023-01-01T00:00:00Z.
