Help with Payment, SMS, WhatsApp and Email Gateways

Hi
I am creating a Saas software where I am giving freedom to users to setup their own

  1. Payment Gateways : Stripe, Paypal, Paystack and Razorpay
  2. SMS Gateways : Twilio, ClickSend, Textlocal
  3. WhatsApp API
  4. Email : Gmail, Clicksend, etc…

How can I add this ability where users can enter their own token IDs and token secrets?

Please help and guide.

Thanks

You can store these values in the User or a separate individual data type linked to the User data type. Set the privacy rules correctly and in order to make calls, use the backend workflows / workflow API

Can you guide or point me towards any particular tutorial as I am new to bubble.io
