UserId | String | Yes |  | Client provided All requests for all resources must include an http header UserId that uniquely identifies the individual initiating the request. Preferably the hpi-person-id of the user would be provided if known, otherwise a userid that allows the authenticated organisation to identify the individual.
FacilityId | String | Recommended |  | Client provided It is recommendedthat all requests for all resources must include an http header Facilityid that uniquely identifies the Facility initiating the request. Preferably the HPI-F id of the Facility would be provided if known, otherwise a FacilityId that allows the identification of the Facility.
x-api-key | Base64URL encoded string | yes (to use the Gateway URL) | KAnHVzZXJJZGVudGlmaWVy4oCdOiDigJx4eXrigJ19 | As per NIA standard, there is an api key requirement. This is used in scenarios like usage plans, etc. API Gateway reads the key and compares it against the keys in the usage plan. If there is a match, API Gateway throttles the requests based on the plan's request limit and quota. Otherwise, it throws an InvalidKeyParameter exception. As a result, the caller receives a 403 Forbidden response. This header is not used by the immunisation Service, only by API Gateway.

X-Correlation-ID | String. UUID recommended, but not required. | no | 123e4567-e89b-12d3-a456-426614174000 this-is-a-valid-id-too |
