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:

👍 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.
