Usage

util_importwqp(url, headers, body, max_retries = 5, trace = TRUE)

Arguments

url

chr string for the Water Quality Portal API endpoint to query

headers

named chr vector of HTTP headers to pass to httr::POST

body

named list of the JSON request body to pass to httr::POST

max_retries

integer indicating maximum number of retries on request failure (default = 5)

trace

logical indicating whether to print retry messages, default TRUE

Value

Details

Used internally with read_importwqp. Retries with exponential backoff on any request or parsing failure (e.g., an empty or malformed response from an intermittent API failure), since such failures are not reliably identifiable by error message alone.
