Usually we don't put newlines between two nested namespace beginnings. 

namespace content {
namespace {

Done.

+namespace {
+
+const char kPaymentAppManifestDataKey[] = "PaymentAppManifestData";
+
+}

[please use gerrit instead, 2016/11/15 20:04:26]

Anonymous namespace should end with "}  // namespace". A lonely "}" on its own
line is confusing to readers.

Done.

All TODOs should have a bug link. The linked bug should keep track of work to
implement this TODO.

Cleaner to use a single statement with a ternary conditional.

callback.Run(status ==  SERVICE_WORKER_OK ? 
payments::mojom::PaymentAppManifestError::NONE :
payments::mojom::PaymentAppManifestError::STORE_MANIFEST_FAILED);

You'd need to clang-format the line.
