Request Headers

You must incorporate the required request headers. The following table defines the request headers.

Request header	Value
`WM_CONSUMER.ID`	Specifies the consumer ID, also called the client identifier. This is the client consumer ID for the OAuth2 client credentials. Contact your Walmart Client Center's Walmart administrator, client administrator, or development lead for this value.
`WM_QOS.CORRELATION_ID`	Specifies the request log identifier. Walmart GoLocal uses this value to log requests and error situations. This optional header can be any value. Examples: 2398685 f74bf-b8ca-447d-8338-966dd751445f
`Authorization`	Specifies the bearer token received from the access token call. The authorization is in this format: Bearer <access_token> .
`Content-Type`	Specifies the content type. The Walmart GoLocal API uses JSON exclusively to transfer information to and from Walmart resources. The `Content-Type` header will always be `application/json`, ensuring requests are recognized by Walmart resources and API requests. The header is not required for GET requests.
