What is API Authentication?

API authentication is a process of verifying the identity of a user or process on an API. Authentication can be one-way or two-way, depending on what information you are seeking to validate. One-way authentication only authenticates the requestor's identity, while two-way authentication authenticates both the requestor and the server. It’s important to remember that APIs are shared resources, which require this type of security in order to prevent unauthorized access.

What our customers say

I chose 500apps because of their value and incredible superior customer service. They really care about small-to-medium sized organizations like ours, whether you're very CRM experienced or lightly so. Every business needs a CRM these days. Compared to HubSpot or Fusion Marketing, they really present a better value and are quite robust yet simple to use. Very pleased!

I love 500apps. It's a perfect solution for startups. The price is right and the system does all I need it to. I had a small issue and called the customer service line. I was really impressed being able to speak with the team all the way from Australia. They resolved my issue immediately and were very nice to deal with. I highly recommend this solution. 500apps is excellent for startups who can't afford the high prices of alternative solutions out there.

500apps is a pretty compressive system for a good price. Plenty of integrations. Sales, marketing and help desk automation. I love that it integrates with IMAP and the chrome widget is brilliant for pulling in LinkedIn data. I've found the customer service incredibly responsive. These guys really care about their reputation.
