API Guide





·       API_KEY

o   required

·       format

o   optional

o   Possible Values: csv|json

o   Default Value: csv

·       incremental

o   optional

o   Possible Values: 0|1

o   Default Value: 0

o   Explanation: If set to 1, the incremental feed will be called, ie. only new, updated or deleted offers since your last extract will be returned.

·       last_extract

o   optional

o   Possible Values: UNIX Timestamp in seconds

o   Example Value: 1553990400

o   Default Value: Your last extract datetime as recorded by our system.

o   Explanation: If you are calling an ‘incremental’ feed, then Coupon API returns only the new, updated & deleted offers since your last extract. You can use this field to pass a custom value instead of using the last extract recorded by our system.

·       off_record

o   optional

o   Possible Values: 0|1

o   Default Value: 0

o   Explanation: Our system keeps a track of your API calls to understand which offers to send when an ‘incremental’ feed is called. If in case, you want to test the API while it is already being used on a live website, you can set this parameter to 1 in your test website. This way, your last extract time will not be updated in our system, and hence there will be no disturbance to your live website. Note that this call will still be counted in your daily limit.
