# config.json
A template for an Airnode's configuration file. Below are notations to help explain contents of the template.
<FILL_*>, <FILL_NUMBER>, <FILL_BOOLEAN>: The value added is independent from other fields and a value is needed unless otherwise indicated. These values are not considered secret unless you want them to be.<FILL_OPERATION_PARAMETER_1_NAME>: If two fields contain the same expression, use the same value in them because they are referencing each other. Usually these are not considered to be secret.${CHAIN_PROVIDER_URL}: Interpolated values ${} that should be added tosecrets.envthough it is not required.
Consider the following relationships.
ois[0].titleis related totriggers.rrp[0].oisTitle.ois[0].apiSpecifications.paths[path][method].parameters[0].inis related toois[0].endpoints[0].fixedOperationParameters[0].operationParameter.inois[0].apiSpecifications.paths[path][method].parameters[1].inis related toois[0].endpoints[0].parameters[0].operationParameter.in
