Base44

Add email sending with SendPing to a Base44 app using backend functions and a stored API key.

Base44 is a platform for building apps with AI. You can add SendPing to a Base44 project by asking the chat to add email sending with SendPing.

This integration requires backend functions, available on the Builder tier and above, because the API key must be used server-side.

1. Wire up email in Base44

If adding to an existing app, enable backend functions, then ask the chat:

Add SendPing email sending to my app. Prompt me to provide the API key, store
it server-side as SENDPING_API_KEY, and send a welcome email to new users by
POSTing to https://www.sendping.co/api/emails with an Authorization: Bearer header.

In Node.js backend functions you can install the official sendping SDK (npm install sendping) and call mb.emails.send(...). In other runtimes the backend function calls the SendPing Emails API over plain HTTP.

2. Add your SendPing API key

However you add email to your project, create a SendPing API key in the dashboard and store it as a backend secret named SENDPING_API_KEY.

Do not share your API key or expose it in client-side code. Keep it in a backend function secret.

3. Add a custom domain

By default you can only send email to your own address. To send to other recipients, add and verify a custom domain, then update the from field in the backend function to use an address on that domain (or ask the chat to update it).
