user15143: 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?

user75001: The other suggestions already cover a couple of providers with API's.
Much of what will need to be done depends on your storefront frontend/backend. For example, if you use CubeCart there are payment gateway extensions, some of which may enable Bitcoin. (I am not affiliated with any)

user63569: Hard Solutions would be building your payment system from scratch e.g. generating bitcoin addresses and checking them for payments and then confirm the order. 
but if you don't want to get your hands dirty then you may use some third parties such as blockchain.info. 
the problem with third parties is stability. blockchain.info is free and has a nice API. 

user84485: 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".
