Case Study: Crédit Mutuel Arkéa: 95% of users save time daily with Postman
Key results
The challenge
Crédit Mutuel Arkéa, a French banking and insurance group, needed internal teams and external partners to collaborate on APIs without friction, including non-technical users. Integrating partners onto products such as its instant payment offering was slow.
The solution
The group standardized API work on the Postman Enterprise plan, using Collections, API documentation, mock servers, and Partner Workspaces alongside its GitLab integration to design, share, and validate APIs with partners.
“Our external partners and internal teams collaborate with ease on Postman. Its graphical interface means non-technical users are equally comfortable with testing and validating APIs.”
JPJonathan PennecHead of API Management, Crédit Mutuel Arkéa
The results, in context
After two years of use, 95% of users reported that Postman saves them time every day, and the platform handled around 20,000 API calls per month across more than 350 workspaces. Customer integration time for its instant payment product fell from one week to one hour.
