How do I connect my online store to the blockchain? I have an online store for which I want to be able to accept bitcoin.

I believe that what I need is an API that will connect my store to the blockchain. If not, the question below would relate to what I need.

I need a developer who can handle both ends of the project, that is identifying or building the right API to connect to the blockchain, and connecting the API to my storefront. How would I find the right application and a reasonably good developer?
If you want to accept payment by Bitcoin or Bitcoin API in your application then you can use "blockchain.com" 's API in your application. So that you can build function and module as per your requirement and also if you want to build your eCommerce platform from scratch then you can use "CryptoWoo.com".
