If you have send some custom data for every order you can use multiple different parameters.
You can pass some free text in `
order_note
` (around 200 characters)Or if your use-case requires you to pass structured data, you can use another field `
order_tags
`.
If you use the `order_tags
` field, you can pass different key-value pairs for every order. Here are some basic things to keep in mind when using this field.
The `
order_tags
` field accepts a collection of key and values.You can set any key and value. The maximum number of keys supported is 6.
We do not have any validations on these key values, and hence it is upto the merchant to pass the correct values.
These custom order tags will also be part of the transaction report which can be downloaded from the merchant dashboard.
We do not display these `
order_tags
` in the merchant dashboard.
