That’s a really common situation, I’ve been there too. In one of my projects we outsourced an API integration because we didn’t want to delay the product launch, and honestly it worked out better than I expected. The external team already knew all the pitfalls, so it saved us weeks of trial and error. Later I came across this article that breaks down the pros and cons of both in-house and outsourcing, and I think it might help you see the bigger picture: https://patternica.com/blog/third-party-api-integration. For me the main criteria are complexity of the API, availability of skilled devs on the team, and how critical the integration is for the core business. If it’s something absolutely central, I’d rather have my own people handle it, but for anything secondary outsourcing often ends up being more efficient.
