I have a queue paused problem

Check the documentation with the main errors that cause your queue to be paused.

I removed a subscription/installment because I didn't receive the webhook?

Asaas webhooks refer to the charges themselves and not to subscriptions or installments. In this case, what you will receive are the PAYMENT_DELETED of the charges that belonged to a particular subscription or installment plan that was removed.

How important is it to use webhooks in my integration?

There are several reasons to use webhooks instead of more traditional communication methods like regular API queries:

1. Real-time notifications: Allow you to be notified instantly when a specific event occurs in a system, without the need to repeatedly query the system at regular intervals.
2. Efficiency: eliminates the need for repeated queries, reducing the load on servers and improving the overall performance of the systems involved.
3. Simplicity: they simplify the integration process between systems.
4. Flexibility: Webhooks allow for a wide range of use cases and integrations between different systems.
5. Better user experience: By receiving real-time updates, users can enjoy a more dynamic and interactive experience in applications and online services.

What does the “Authentication Token” mean in the webhook settings?

To add an extra layer of security, you can add an authentication token that will be fired in the header of all requests sent from Asaas to your application. This token will be sent in the asaas-access-token header. Thus, you can prevent and treat only received POSTs that contain this header specifically, avoiding any inappropriate triggers against your endpoints.
