What do you like best about Postcoder?

Easy to use API that's fast and reliable, reasonable pricing. Review collected by and hosted on G2.com.

What do you dislike about Postcoder?

Email alerts for increases in usage can be overzealous (e.g. alert because a site has used 10 lookups in one day instead of the usual 1 or 2 lookups). Review collected by and hosted on G2.com.

Response from Jasmine Robinson Madden of Postcoder

We're very pleased to hear that you find our API easy to use and reliable, and that it has been beneficial for your clients. We appreciate your feedback about the email alerts - we'll take it into account as we refine our notification system.

In the meantime, email alerts can be updated in the Postcoder Admin Area if you wish, follow Account Settings > Alerts to customise the trigger point for receiving high usage alerts. Please get in touch with our Sales team sales@alliescomputing.com if you need assistance with this.

Many thanks for taking the time to leave a review!

"Straightforward and easy to use"
4/5
What do you like best about Postcoder?

The dashboard is a clean dashboard, clearly shows the usage of the credits. Review collected by and hosted on G2.com.

What do you dislike about Postcoder?

The date selection of the usage dashboard is not that intuitive, it took me a couple of goes to work out how to select a start and end date, but that may be just me.

Also, the show all requests drop down seems to be showing all the same requests for each category i.e. if I select address lookup and then select bank validation, the daily numbers are the same - then the daily numbers are the same for the other categories such as email validation, OTP validation etc. Review collected by and hosted on G2.com.

What do you like best about Postcoder?

The excellent API documentation. They have an extensive range of API services available and the implementation is easy with their accurate documentation Review collected by and hosted on G2.com.

What do you dislike about Postcoder?

I've never liked the credit package model, having to buy a specific amount of lookups in advance. A pay for what you use monthly billing cycle would be far better Review collected by and hosted on G2.com.

Response from Jasmine Robinson Madden of Postcoder

Thank you for the positive feedback on our API documentation and services, we're particularly pleased to hear you find our documentation accurate and useful. We appreciate your input on the credit package model and will consider it for future enhancements. We do have a monthly billing option, with a fixed amount of credits per month and excess use available. Please get in touch with our Sales team and they will be happy to help you get on a plan that best meets your needs. Thank you for taking the time to leave a review.
