Workflows allows you to call APIs, whether from or hosted on Google Cloud, or any external API in the wild. A few days ago, for example, we saw an example on how to use the SendGrid API to send emails from a workflow. However, in that article, I had the…

Following up the article on writing and reading JSON files in cloud storage buckets, we saw that we could access the data of the JSON file, and use it in our workflow. Let’s have a look at a concrete use of this. Today, we’ll take advantage of this mechanism to…

For notification purposes, especially in an asynchronous way, email is a great solution. I wanted to add an email notification step in Google Cloud Workflows . Since GCP doesn’t have an email service, I looked at the various email services available in the cloud: SendGrid, Mailgun, Mailjet, and even ran…

Workflows provides several connectors for interacting with various Google Cloud APIs and services. In the past, I’ve used for example the Document AI connector to parse documents like expense receipts, or the Secret Manager connector to store and access secrets like passwords. …

As I was working with my colleague Sara Ford on testing the Cloud Functions runtimes for the upcoming “second generation” of the product, rebased on the Cloud Run platform, I wrote a few simple functions for the Java runtime. In one of those Java functions, I wanted to use Google…

In the two previous episodes, we saw how to create and call subworkflows , and we applied this technique to making a reusable routine for logging with Cloud Logging. However, there’s already a built-in function for that purpose! So let’s have a look at this integration. To call the…

Workflows are made of sequences of steps and branches. Sometimes, some particular sequence of steps can be repeated, and it would be a good idea to avoid error-prone repetitions in your workflow definition (in particular if you change in one place, and forget to change in another place). You can…

Time to come back to our series on Cloud Workflows. Sometimes, for debugging purposes or for auditing, it is useful to be able to log some information via Cloud Logging. As we saw last month, you can call HTTP endpoints from your workflow. We can actually use Cloud Logging’s REST…

In previous episodes of this Cloud Workflows series, we’ve learned about variable assignment , data structures like , and switch conditions to move between steps, and expressions to do some computations, including potentially some built-in functions. With all these previous learnings, we are now equipped with all the tools to…
