android pay - Google wallet API Integration questions -


i new integrate google wallet , there confusion , questions related given below:

  1. is possible add multiple items google wallet?
  2. how handle discount api?
  3. what's parameter in jwt response on postback url success , failure transaction?
  4. is refund functionality available transaction api call?

anyone have idea this. in advance.

can clarify specific api (instant buy or wallet digital)?

is possible add multiple items...

  • digital - no, can "bundle", see this post clarification.

  • instant buy - it's "layer" on top of (pre) existing purchase/ordering processes , handles (just) payment data of google wallet user. "order details" control. see sample of data send.

discounts api

by api - no. can pass whatever (pre-calculated) value in both apis.

success vs. failure postback

  • digital - google send http post server url on successful transaction. see #5: "google sends http post message postback url whenever purchase completes..."

  • instant buy - not relevant. you processing transaction, unlike in digital google is. instant buy in nutshell provides web site, secure access google wallet user's data. need have own merchant account/processor, pci compliant, etc. said, have success or failure info you have send google - need know if have processed or not (yup, it's other way around).

refund api

by api - unless googler says otherwise, afaik, not @ time, both apis.

on note, instant buy, it's unclear me how "inform google" when performing credit or refund. still "private api" (not ga) haven't seen "guts". it's understood since merchant uses own processor credit/refund same procedure, letting google "know" (days/weeks after fact) have no actual info on..sorry...i can assume "button" in merchant center instant buy, that's guess....

hth....
