Add support for manual settlements

[visini]

Currently, transactions are auto-settled by default. However, in some cases, settlement of transactions should be delayed. This adds support for that, allowing setting auto_settle: false when authorizing a transaction.

transaction = datatrans.json_transaction(
  refno: 'ABCDEF',
  amount: 1000,
  # ...,
  auto_settle: false
)

looks good!

I remember we talked about a second feature that you need in order to use the gem. Is this still the case or can I ship a release with only this change?

Thank you @andyundso! 😊

These changes are already useful, since it's now possible to set auto_settle: false and then later settle transactions, for example (manually) via the Datatrans UI.

However, I'm currently working on adding support for the settle endpoint of the JSON API, which is currently missing, via...

• Add support for card param for authorize visini/datatrans#2
  • This is "preparation" for authorizing transactions via an alias
• Add JSON::Transaction::Settle visini/datatrans#1
  • With this we can settle transactions "programatically" using the gem

I want to validate if everything works as expected by further testing it in the context of my use case and in the sandbox environment. So far so good. I'd also like to add a section to the Readme (which should tie together these changes in a nice example).

As soon as everything is ready, I'll open these respective PRs against this repo. I think in the next couple of days. Hope that's okay, and thank you!

all good, then I wait with the release and looking forward to your contribution.

@andyundso turns out I was on the wrong track after all... I found out that confusingly, JSON::Transaction::Authorize does not actually talk to the authorize endpoint (it is clearly stated in the class, but I didn't read it properly 😓).

Therefore I'm proposing to add the following "missing pieces":

• Add JSON::Transaction::Settle #52
• Add JSON::Transaction::MerchantAuthorize #53

Thank you for your feedback and for preparing a release, much appreciated! 🙏😊
