Troubleshooting
Seeing "400 Bad Request" or "Invalid redirect_uri value" errors with LINE Integration?
When you try to connect your service with LINE, you might sometimes see error messages like "400 Bad Request" or "Invalid redirect_uri value." This usually happens when there's a mismatch in the "return address" (URL) settings between your service and LINE.
Here’s how to check and fix this.
Why does this error occur?
This error occurs because after LINE verifies your information, the internet address (URL) where LINE should send you back doesn't match what LINE expects and what your service is set up to use.
What to check to resolve this
The main thing to check is whether the correct "Callback URL" is registered in the LINE Developers Console (LINE's settings screen for developers).
Open the LINE Developers Console
Go to the LINE Developers Console.
(If you're unsure how to access this, please check with your service administrator.)
Select the relevant "Channel"
Choose the "LINE Login" channel you are using for the integration.
Check and set the "Callback URL"
In the channel settings, find an item called "Callback URL."
Please set the following URL here.
https://api.jicoo.com/v1/integrations/line/auth
Other Points
Exact URL match is crucial: The "return URL" that your system tells LINE and the "Callback URL" you set in the LINE Developers Console must be an exact match, including capitalization.
Differences between environments: If you use different internet addresses (domains) for a testing environment and your live (production) environment, you'll need to set the correct Callback URL in the respective LINE Channel settings for each environment.
I can't register as a friend after logging in to LINE.
You need to set up an official LINE account linked with the Add Friends option.
Error message. {“data”: “Failed to get LINE channel access token”, “errors”:{}, ‘errorMessage’: “Internal Server Error”}
There is a discrepancy in the MessagingAPI/channel ID and MessagingAPI/channel secret settings.
I set the LINE Channel app type as “Native App” for Jicoo integration, but I cannot use it.
I cannot set the LINE integration settings with Jicoo if the app type is “Native App”.
If you wish to link Jicoo and LINE, you must select “Web App” as the app type only.
Jicoo's LINE login functionality is built upon a system that authenticates on the website (Web App). Therefore, the settings on the LINE side must also be registered as a “Web App” to match this mechanism, otherwise the authentication flow will not function properly.
What happens if I select “Native App”?
An error will occur during the integration process and the login to Jicoo will not be completed successfully.
Due to LINE specifications, once a channel is created as a “Native App”, it cannot be changed to a “Web App” later. In this case, you will need to re-create a new channel with the correct settings (“Web App” only).
Therefore, please be sure to check “Web App” only when configuring.
In the LINE Settings, the “Email Address” checkbox is checked for the information to be retrieved, but the email address is not retrieved when the guest logs in to LINE.
The possible cause is that the permission to retrieve email addresses is “Not Applied” in the LINE channel.
In order to obtain the guest's email address when they log in to LINE, the following two settings must be made.
LINE Settings > Information to collect “Email address” is checked
“Authorization to retrieve email address” for the channel has been applied for in the console of LINE Developers.
