As I look at modern development stacks, certain must-have API integrations seem to be almost universal. For example, authentication APIs like Auth0 or Firebase Auth are pretty much standard now. Similarly, payment processing APIs like Stripe or PayPal are must-haves for any commercial project.
But I'm curious what other must-have API integrations you consider foundational. What integrations are so common that not having them would be considered unusual or problematic?
I'm particularly interested in integrations that have become de facto standards in specific domains. For example, in e-commerce, shipping API integrations like Shippo or EasyPost seem essential. What other domains have clear must-have API integration solutions?
