Automate repetitive tasks using Postman Flows

You can use Postman Flows to complete repetitive tasks. Businesses often need to delete emails from multiple systems. Logging in, searching, and deleting emails from multiple locations can be time consuming. This tutorial shows you how to create a flow that deletes an email from three locations each time you run the flow.

For this tutorial, the locations are Stripe.com, Brevo.com, and a Postman mock server that acts as a hypothetical internal system.

You can find the complete flow in the DevOps Flows workspace.

Prerequisites

• A Stripe account with a customer with the test@email.com email address.
• A Brevo account with a contact with the test@email.com email address.
• A Stripe secret key.
• A Brevo API key.

Fork the collections and environment

Fork these collections from the DevOps Flows workspace into your workspace:

• Stripe API

• Brevo

• customer-list

Fork this environment into your workspace:

• gdpr-delete-email

In the gdpr-delete-email environment, replace <your-brevo-api-key> with your Brevo API key. Replace <your-stripe-secret-key> with your Stripe secret key.

Create the flow

1. Part one: Delete the contact from Stripe

   • Create a new flow. Add a String block and enter test@email.com.

   • Connect a Create Variable block and enter Customer Email.

     

   • Connect three HTTP Request blocks to the Start block, arranged vertically.

     

   • In the top HTTP Request block, select Stripe API > Customers > Search customers.

   • Select the gdpr-delete-email environment.

   • For the email variable, add a Get Variable block and click Customer Email.

     

   • Create an If block next to the HTTP Request block. Add a Select block to the If block and change value1 to contacts.

     

   • Connect the HTTP Request block’s Success output to the If block’s contacts and Data inputs. Next to contacts, select body.data. In the FQL window, enter $count(contacts) > 0.

   • Connect the If block’s FALSE output to a Display block.

   • Rename the Display block Contact not found and select Boolean from the dropdown list.

   • Connect the If block’s TRUE output to an HTTP Request block. Select Stripe API > Customers > Delete a customer.

   • Also connect the If block’s TRUE output to the HTTP Request block’s customer_id input and select body.data.0.id.

   • Connect the HTTP Request block’s Success output to a Display block.

   • Rename the Display block Contact deleted and select Boolean from the dropdown list.

     

2. Part two: Delete the contact from Brevo

   • In the middle HTTP Request block, select Brevo > Contact management > Contacts > Get a contact’s details.

   • Select the gdpr-delete-email environment

   • For the email variable, add a Get Variable block and click Customer Email.

   • Connect this block’s Success output to another HTTP Request block and select Brevo > Contact management > Contacts > Delete a contact. Also connect the middle HTTP Request block’s Success output to the new HTTP Request block’s contact_id input and select body.id.

     

   • Connect the Delete a contact block’s Success output to a Display block. Rename the Display block Contact deleted and select Boolean from the dropdown list.

   • Connect a Display block to the Get a contact’s details HTTP Request block’s Failure output. Rename the Display block Contact not found and select Boolean from the dropdown list.

     

3. Part three: Delete the contact from an internal system

   • In the bottom HTTP Request block, select customer-list > customer/email.

   • For the email variable, add a Get Variable block and click Customer Email.

   • Connect the Success output to an HTTP Request block and select customer-list > customer/id.

   • Also connect the customer/email HTTP Request block’s Success output to the id input and select body.id.

   • Connect the customer/id HTTP Request block’s Success output to a Display block. Rename the Display block Contact deleted and select Boolean from the dropdown list.

   • Connect the customer/id HTTP Request block’s Failure output to a Display block. Rename the Display block Contact not found and select Boolean from the dropdown list.

     

Run the flow

Select Run. The flow finds and deletes the contact with the test@email.com email address on Brevo, Stripe, and the internal system. When the contact is deleted, the Contact deleted Display block shows True. If there is no contact with that email address, the Contact not found Display block shows False.
