What can you do with Alegra on Tray.ai?
Alegra is cloud accounting and electronic invoicing software for small businesses in Latin America and Spain, covering sales, expenses, inventory, banking and payroll. Tray.ai connects to Alegra through the HTTP Connector, so your workflows can call the Alegra API alongside the rest of your stack.
- When Alegra sends “New invoice”, record the sale in your CRM against the customer.
- On “New client”, create the account in your CRM so sales and finance share one record.
- Create an invoice when a deal closes in your CRM, so billing starts the same day.
- Create a payment in Alegra when your payment processor confirms a charge.

Set it up
Connect Alegra to Tray.ai
Each step uses Alegra's own API details, from its documentation.
Step 1
Save Alegra's username and password
Save the credentials Alegra gives you as a Tray.ai authentication. The HTTP Client sends them as basic auth. They stay out of the workflow and out of the logs.
Step 2
Point the HTTP Client at the API
Add an HTTP Client step and use https://api.alegra.com/api/v1 as the base URL. Or paste a cURL example from Alegra's API docs, and Tray.ai fills in the method, URL, and headers.
Step 3
Start with “List invoices”
It's one of 23 documented actions, under Invoices. The response comes back as data the next step can map into your other apps.
Step 4
Start workflows from Alegra events
Give Alegra the URL of a Tray.ai webhook trigger. “New client” can then start a workflow, and so can 2 other events.
