+# Timeout
+
+Timeouts can be set by partners when making requests to our API. This allows partners to control the maximum duration for which they are willing to wait for a response from our server.
+
+## Timeout Durations for OY's API
+
+Below is the list of timeout durations for OY's API:
+
+API | Timeout in seconds 
+---------- | ------- 
+E-Wallet Aggregator | 60 
+
+## Setting Timeout
+
+Partners can set the timeout by including the `timeout` parameter in the request headers. The value of the `timeout` parameter should be specified in seconds.
+
+## Example
+
+```http
+POST https://partner.oyindonesia.com/api/e-wallet-aggregator/create-transaction
+Host: partner.oyindonesia.com
+Content-Type: application/json
+X-Oy-Username: yourusername
+X-Api-Key: yourapikey
+Timeout: 60
+```
+
+In this example, the partner is setting a timeout of 60 seconds for the request to POST /api/e-wallet-aggregator/create-transaction. Please note that OY's server will respond within this specified timeout duration.
