The Pismo platform supports server-to-server authentication using stored credentials. This is similar to a username/password system, except that instead of a username and password, you provide a server_key and a secret_key. For requests on behalf of a specific account, you also need to provide an account_id.

The Pismo platform's Passport API allows server-to-server authentication, so a proxy server can execute some operations. For example, in the case of a person using an app on a mobile device or an operator using a CRM system, the authentication process should go through a proxy server.

Generating authentication keys

Before you can log in to the Pismo platform, you need a server key (server_key) and a secret key (secret_key). In Pismo Console, click Create key. This generates both keys. You must be an admin to use Pismo Console.

🚧

Secret key is displayed only once

After you generate your secret key, you should save it somewhere. Otherwise, you'll have to generate a new one the next time you need to provide it.

Initial authentication

When first logging in from an external server, you need to send the Pismo platform a request to create an access token. Pismo will return a JSON Web Token (JWT). You must include your server_key and secret_key in the body of the request.

If you intend to make calls on behalf of a specific account, you must also include the corresponding account identifier (account_id). If you provide an account identifier, subsequent calls can only access resources that belong to that particular account.

You can find a complete list of the endpoints that you can use for requests in the API Reference. For a list of the endpoints that require the account identifier, see Endpoints that require an account-specific token.

To request an access token, use the following endpoint.

Get basic authentication access token
Request body:

{
  "server_key": "<server_key_provided>",
  "secret_key": "<server_secret_key_provided>",
  "account_id": <account_holder_identifier>
}

The following code shows an example of a response body for this request. It includes an access token (token), which you can use as an authorization header in future requests.

  "server_key": "<server_key_provided>",
  "tenant": "<tenant>",
  "program_ids": [],
  "roles": [
    "account-server",
    "onboarding-server",
    "crm-server",
    "crm-operator"

}

Renewing an expired token

The access token has a predefined lifetime. There is an exp field in the JWT that contains the date/time of expiration in Unix Epoch time. After the access token expires, the Pismo platform rejects additional requests. If you make a request using an expired token, the request returns Unauthorized. You should check for this message in your code and request a new access token when you receive it.

📘

You can use the JWT Debugger website to view the fields in a JWT. Holding the mouse pointer over the decoded exp value displays it as a human-readable date/time.

If you need to access the field values in your code, see Parsing the JWT.
