Async Execution

It is possible to invoke a function through its HTTPS Endpoint without having to wait for a response. To do this, simply 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

It is a good idea to use async execution when sending data to an UbiFunction from external platforms like Particle.io or LoRaWAN Network Servers. This prevents failed or timed-out requests, which could affect server rating.

For instance, Particle skips webhook attempts when too many time-outs or 4xx / 5xx HTTP status codes occur, which could translate into data loss for your IoT application. Learn more about Particle's API Limits and Policy.
