Circle

I wish I could be as positive as the other posters, from what look to be about a year ago. My Circle integration is at an impasse, just a couple months in. Circle support give me implausible excuses for serious DX issues with their API, and no estimates or fixes for acknowledged API errors. To their credit, they have acknowledged that I must be frustrated! I truly wish I weren't considering other platforms at this time, for what seem like pretty small matters of code and/or database performance. Most troubling, is the failed support narrative of, "how do other people use this?" My conclusion is, they can't use it, either. My overall take on this product is, if it works out of the box for you, it is probably a great deal. If your application depends on integration, tread very carefully.
