Isabel Connect Create First Access Token and Refresh Token

See more Ibanity Examples

Creates your first access token and refresh token. Once created, the refresh token can be used to get a new access token after it expires, or before it expires. React Native

  // This example assumes the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  const http = new Http();

  // Implements the following CURL command:

  // curl -X POST https://api.ibanity.com/isabel-connect/oauth2/token \
  // --cert certificate.pem:qwertyuiop1 \
  // --key private_key.pem  \
  // -H "Content-Type: application/x-www-form-urlencoded" \
  // -H "Accept: application/vnd.api+json" \
  // -H "Ibanity-Idempotency-Key: af621a8f-f74b-41a2-b011-336997633df4"  \
