Every device must provide a valid access token when it sends telemetry to HERE Tracking. Tokens must be obtained from HERE Tracking upon the device login. In order to be able to login, the device must be associated with a user project, i.e. claimed by an end user.
HERE Tracking requires the device token requests to be signed. The signature method uses the OAuth 1.0 standard. For more information on this standard, see the OAuth Core 1.0 specification.
IMPORTANT You must create a new signature for each device access token request to HERE Tracking. Signatures can only be used once.
For the available authentication options, see the Identity & Access Management Developer Guide.
