Quickstart: Mint SBC on testnets
Use the Brale API to mint SBC on Polygon Amoy Testnet.
1. Sign up for a Brale account
Visit Brale's signup page to create an account. Testnet accounts are free, and signup takes less than 30 seconds.
2. Create an Application
Create an application on the Settings page in the Dashboard. Select testnet access, and toggle on mint and redemption permissions. You should store your secret, as it’s only shown once during generation.
To help navigate the API, you can download our OpenAPI Spec, or our Postman Library here.
You can also use the Brale CLI to streamline common interactions with the API.
3. Authenticate
Brale uses OAuth2 with the client_credentials
grant type for secure access to our APIs. Sending a request to the Auth endpoint will return a bearer token to be used on all subsequent calls. The Authorization header uses Basic HTTP Authentication and requires encoding your client_id
and client_secret
into a Base64 format.
curl --request POST \
--url https://auth.brale.xyz/oauth2/token \
--header 'Authorization: Basic ${BASE_64_OF(client_id:client_secret)}' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data grant_type=client_credentials
See Authentication for additional details.
