Set up a Firebase Remote Config project

You can set up your app to use Firebase Remote Config with in-app default values, deploy your app, and then later set up the Firebase project associated with your app to override those values. To learn more about Remote Config, see Remote Config introduction .

Add or edit a parameter

1. On the  Firebase console  navigation bar, click  Remote Config.
2. Add a parameter or choose a parameter to edit:
   • To add a parameter:Click  Add Parameter.
   • To edit a parameter:Click the parameter you want to change.
3. In the  Parameter field, enter (or edit) the name of the parameter. This must be the same as a Remote Config parameter key that you use in an app that is associated with this project.
4. In the  Default Value field, enter (or edit) the server-side default value for the parameter, or leave it as an empty string.

   Note:You can also click the Other empty valueslist and choose No valueto create a parameter with no server-side default value. This means that apps that use this parameter will use the in-app default value for this parameter. However, a conditional value will still override the in-app default if the associated condition evaluates to true .

5. (Optional) To add conditional values for the parameter, click  Add value for condition, and then select a condition or click  Create New Condition. Follow the instructions provided below under  Add or edit a condition  to add a condition. Then, enter the conditional value.

   Note: When more than one condition associated with a parameter's conditional values evaluates to true , the first condition shown on the Conditionstab takes priority. You can change the priority of conditions .

6. To save changes to the parameter click  Add Parameter or  Update.
7. Click  Publish to publish changes to the Remote Config settings for this project, making those changes available to apps that use this project.

Add or edit a condition

You can add or edit conditions after you add your first parameter, or while adding or editing parameters.

1. On the  Firebase console  navigation bar, click  Remote Config, and then click  Conditions.
2. Add a condition or choose a condition to edit:
   • To add a condition:Click  New Condition.
   • To edit a condition:Click the condition you want to change.
3. In the  Define a new condition dialog, enter (or edit) the title for your condition.
4. (Optional) Select a color that you can use to keep this condition and similar conditions organized.
5. Under  Applies if…, do the following to update your condition:
   • Click add (+) to add a rule to the condition.

     For each rule, choose the rule type, an operator (if available), and a value. See  Parameters and conditions  for information about the different types of available rules.

   • Edit existing rules by changing the rule type, operator or value.
   • Click delete (x) to remove a rule from the condition.
6. To save changes to the condition click  Create Conditionor Update Condition.
7. Click  Publish to publish changes to the Remote Config settings for this project, making those changes available to apps that use this project.

Change the priority of a condition

A parameter will often have more than one conditional value with a condition that evaluates to true . To determine which value is applied to a parameter, conditions are prioritized with the top condition overriding conditions shown in a lower position on screen. You can change the priority a conditions by reordering it on the Conditionstab.

1. On the  Firebase console  navigation bar, click  Remote Config, and then click  Conditions.
2. Use the double line handle ( =) to drag the condition to a new position.
3. Click  Publish to publish changes to the Remote Config settings for this project, making those changes available to apps that use this project.

Delete a parameter or condition

1. On the  Firebase console  navigation bar, click  Remote Config.
2. Click Parametersor Conditions.
3. Click the parameter or a condition, and then click the trash can icon in the lower left corner.
4. Click  Publish to publish changes to the Remote Config settings for this project, making those changes available to apps that use this project.

Search parameters and conditions

You can search your project's parameter keys, parameter values, and conditions from the Firebase console using the search box at the top of the Remote Config Parameterstab. This full-text search feature is case-sensitive.

1. On the  Firebase console  navigation bar, click  Remote Config.
2. Click Parameters, and then enter your search term in the search box at the top of the Parameterstab.
