The most important API metric is time to first call
Publishing an API isn’t enough for any startup: Once it’s released, the hard work of cultivating a developer base begins.
Postman’s head of Developer Relations, Joyce Lin, wrote a guest post for Extra Crunch based on the findings of a study aimed at increasing adoption of APIs that utilize a public workspace.
Lin found that the most important metric for a public API is time to first call (TTFC). It makes sense — faster TTFC allows developers to begin using new tools quickly. As a result, “legitimately streamlining TTFC results in a larger market potential of better-educated users for the later stages of your developer journey,” writes Lin.
This post isn’t just for the developers in our audience: TTFC is a metric that product and growth teams should also keep top of mind, they suggest.
“Even if your market is defined as a limited subset of the developer community, any enhancements you make to TTFC equate to a larger available market.”
