Async execution

You can invoke a function through its HTTPS endpoint without waiting for a response. To do this, add the ?_blocking=false parameter to the URL:

Request URL

https://parse.ubidots.com/prv/username/my-function?_blocking=false

Async Function Response

HTTP/1.1 202 Accepted
Content-Type: application/json

{"activationId":"653ca08ce2104290bca08ce21002909c"}

👍 Particle Webhooks

Use async execution when sending data to a UbiFunction from external platforms such as Particle.io or LoRaWAN network servers. This helps prevent failed or timed-out requests, which can affect server ratings.

For example, Particle skips webhook attempts after too many timeouts or 4xx/5xx HTTP status codes. That can lead to data loss in your IoT application. Learn more about Particle's API limits and policy.
