Headers

The AgSync platform has specific Request and Response headers.

Request Headers

The following table shows the request headers that AgSync may use when accepting requests. Not all APIs implement these headers.

Header	Type	Description
Authorization	string	Authorization header for the request. This should be a bearer access token retrieved from the authorization server.
Accept-Language	"en"	Some APIs support a preferred language for the response.
Content-Type	string	Mime type of the request body. Required for PUT/POST/PATCH.
Prefer	return=minimal, return=representation	If the return=minimal preference is specified, the service should return an empty body in response to a successful insert or update. If return=representation is specified, the services should return the created or updated resource in the response. Currently not all services respect this header. If this header is omitted in the request the default used is return=minimal.
Accept	mime type	The accepted response type, either application/json or text/xml
If-None-Match	"string"	A ETag that the client can specify to make sure a request runs once. This value is a string of ASCII characters placed between double quotes. Not all services use this header. Check service documentation for specific details.

The following table shows the response headers that AgSync may use when serving responses. Not all APIs implement these headers.

Header	Required	Description
Date	All responses	Timestamp the response was processed, based on the server's clock, in RFC 5322 date and time format. This header MUST be included in the response. Greenwich Mean Time (GMT) MUST be used as the time zone reference for this header. For example: Wed, 24 Aug 2016 18:41:30 GMT. Note that GMT is exactly equal to UTC (Coordinated Universal Time) for this purpose.
Content-Type	Most responses unless no content is returned	The content type of the data returned.
Location	PUT and POST	The URI of the resource.
