The API based drivers are primarily very simple and quicker than any other SMTP servers All the API driver’s basic requirement is that it MUST have the HTTP library be installed for all your applications. You may install by adding the following line to your composer.json file:

The purpose of the v3 Mail Send endpoint is to simplify processes that significantly reduce the completion time of our RESTful Web API v3 software.

As we discuss today the public availability of v3/mail/send endpoint, our objective is to share with our global customers, aspiring developers, the latest development and would want their support for we to want them to spend time structuring their apps and accelerating their businesses worldwide—and not waste valuable time in setting up, handling and maintenance of their email infrastructure.

Are we thrilled to explore what an endpoint ushers us with?

This surely will bring in a million smiles–HandySends v3/mail/send endpoint brings you the key to a new world courtesy of HandySends Web API. 

“Over the last couple of years, our developers have been re-engineering the current API to come up with an application that will make integrations for the users easy. This will also allow users to create, build robust and deep, integrated email marketing stacks that will perfectly blend and match the business needs and objectives. 

We are proud to have come up with a version of the API which foresees future demand, you DO NOT need any immediate change or migration–you will have ample time to accept the newer version and by the time it gets stable–we will lend you the extended hand”

This trendsetting new endpoint is the outcome of multiple trend analyses, customer inputs of their personal experience, sharing pros and cons, scrutinizing support receipts, and studying open source concerns. It was important to bring a solution for the haunted global issue about v2 API. We are glad to share, our team of industry expert developers have finally found the right chord and have resolute the pertinent endpoint. 

What does that mean to experience the v3.mail/send is it will allow the developer or user with similar functionalities yet keeping the endpoint constant but adding up large focus on the ‘identity, which is one of the crucial and important facts that will value-add and bring down the ‘work-time for a developer, also known as ‘developer’s developing time”?  Just like crystals can be shaped in any form, the bundle with its adaptability or “tailor-made’ parameters, the clarity and ease of a single email converting into a customized block will be the most emblematic tool used. Of course, the Developer will now opt for the option, where he will simply set his chosen parameter for a fully customized mail send, following on he will also be able to create an identity as per specifications.

HandySends 3C advantages within v#/mail/send: [Freedom to choose, change and convert]

  • Natural instinctual capability to format with added validation and upfront.
  • A clear–structured error report, which accelerates troubleshooting and setting things right
