429 Error

Always Prompting 429 Error

Section titled “Always Prompting 429 Error”

Always prompts a 429 error when performing actions.

Cause

Section titled “Cause”

Spotify returns a 429 Too Many Requests error, which is not Lyricify’s fault.

Solution

Section titled “Solution”

Configure a custom API Client, refer to the Custom Spotify API Client Configuration Guide.
Or wait until Spotify no longer returns a 429 error.

Extended 429 Error

Section titled “Extended 429 Error”

After configuring a custom API Client and using it for a while, a 429 error appears indicating a wait time of several thousand or tens of thousands of seconds.

Cause

Section titled “Cause”

Continuous usage for too long. Using it for several hours continuously, or using Lyricify for several hours without playing songs, increases the chance of encountering an extended 429 error.

Solution

Section titled “Solution”
  • Create a new Client, then log in and authorize again in Lyricify.
  • You can also wait until the 429 error ends.

Some Suggestions

Section titled “Some Suggestions”
  1. Try to avoid continuous usage for too long (over 10 hours), as this can cause the number of requests in a given time to exceed the Spotify API threshold, significantly increasing the likelihood of encountering an extended 429 error.
  2. If you use Lyricify on multiple devices with high frequency, consider creating a separate Client for each device to distribute requests and prevent hitting the threshold limit.
  3. Please close Lyricify when not playing songs. Keeping Lyricify running for several hours (at least 1-3 hours) in this case will lead to a 429 error. (On Android devices, if Lyricify is not in use, please close its background; if not closed, it will continuously send requests, causing an extended 429 error. On iOS devices and some Android devices, it can remain in the background without closing.)
