If you are interested in using an API but wondering about the cost, then the good news is, that there are numerous free APIs to use. Now, let us dig into the steps to use an API when you know it.
Pick the API
The first step of using an API is analyzing and choosing an option. If you already know which API to choose like the big-shot Facebook API or Twitter, then you’re sorted. If not, then try to understand the purpose, and also sort by cost. If money crunch is the issue, then there are numerous free APIs to use that you can select from. This step is followed by sitting calmly and analyzing the API documentation.
Grab the API Key
The second step involves acquiring the API key since it is the key to your identification as a valid client. It will further set access permissions and record ongoing interactions with the API. Though maximum APIs offer the key for free, some might be chargeable.
After signing up, the user is offered one unique identifier. This key is extremely important in marking your security. Ensure that you always have your key private otherwise, there might be a security breach.
