This endpoint allows processing tokenized transactions using the JOSE standard for information security

Prerequisites

Before using this endpoint, a configuration process must be completed on our side using the RSA keys provided by the client:

• Processor's public key

• Merchant's private key

Base URL

https://api.firstoken.co/proxy/jose

Note: In case, you have to make some sandbox tests you must be called from the base URL https://api.firstoken-staging.co/proxy/jose

Headers of the request

Important notes

• Token fields use special syntax depending on the token type:

  • For Permanent Tokens (using detokenization):

    • Card number: {{token:detokenize | extract:card}}

    • Expiration date:

      • Month: {{token:detokenize | extract:expiration | date: MM }}

      • Year: {{token:detokenize | extract:expiration | date: YY }}

  • For Temporary Tokens (using transaction):

    • Card number: {{token:transaction | extract:card}}

    • Expiration date:

      • Month: {{token:transaction | extract:expiration | date: MM }}

      • Year: {{token:transaction | extract:expiration | date: YY }}

Security

• Communication is done through HTTPS.

• Authentication is required via the ft-access-key header.

• Sensitive information is processed using the JOSE standard.
