Seamlines WMS
Overview
The Web Map Service (WMS) returns a raster representation of lines for a given area, based on request parameters.
Authentication
All OGC services accept an API key or a bearer token for authentication.
Bearer tokens
Maxar Oauth bearer tokens can also be used to authenticate API requests. Bearer tokens have a brief duration and must be refreshed frequently.
To authenticate with a bearer token, use the Authorization header:
Authorization: Bearer <Oauth2 token>
Learn about OAuth2 bearer tokens
API keys
API keys can be passed using query parameters or in a custom header. No Authorization header is needed when using API keys.
To use the query parameter method, include this query parameter in your request:
maxar_api_key=<your API key>
The custom Maxar header takes the form of:
maxar-api-key: <your API key>
API keys expire 180 days from creation by default. A custom expiration date can be set but cannot exceed 180 days.
